Definition
A demijohn is a large glass or earthenware vessel with a bulbous body and a narrow neck, typically encased in wicker or other protective material, used to store or transport liquids — most commonly wine, spirits, vinegar, or other bulk beverages. In legal contexts, the term appears almost exclusively in probate inventories, customs and excise records, commercial contracts for the sale of goods, and evidence in cases involving the handling or transport of liquor. It functions as a unit of description for personal property rather than as a term of legal art.
Common Language
Modern common usage (Wiktionary): A large bottle with a short neck, sometimes with two small handles at the neck, sometimes encased in wickerwork.
Historical common usage (Webster's 1913): A glass vessel or bottle with a large body and small neck, inclosed in wickerwork.
The legal and common meanings are essentially identical. The term carries no distinct legal definition — it describes the same physical object in a courtroom that it describes in a warehouse. Its legal significance lies entirely in context: whether a demijohn appears in a will, a bill of lading, a tax schedule, or a criminal indictment determines what questions it raises, not any specialized legal meaning of the word itself.
Why It Matters in Research
Researchers encounter demijohn most frequently in three documentary contexts within historical legal sources.
First, probate and estate records. Demijohns appear routinely in household inventories attached to wills and letters of administration, particularly from the eighteenth and nineteenth centuries. When evaluating an estate's personal property, the vessel's contents — and whether those contents were separately valued — can affect the computation of taxable assets or the distribution of specific bequests. A bequest of "all my wines and spirits" may or may not encompass a demijohn depending on how the inventory characterizes it.
Second, customs, excise, and liquor licensing records. Demijohns figure in excise schedules and licensing disputes because their capacity affects duty calculations. In jurisdictions that taxed spirits by the container or imposed licensing requirements tied to volume, the classification of a demijohn versus a barrel or carboy could have practical legal consequences. Researchers working with nineteenth-century American or British licensing records should be alert to the vessel's capacity varying considerably — typically between one and ten gallons — which affects how it maps onto statutory definitions of taxable quantities.
Third, sale of goods and commercial disputes. In contracts for the delivery of bulk wine or spirits, the demijohn sometimes served as both the container and the unit of measure. Disputes over short delivery, breakage, or contamination may turn on whether the demijohn itself was part of the goods sold or a returnable vessel belonging to the seller.
The historical legal dictionaries are of limited direct use here. Anderson's Dictionary of Law does not contain a dedicated entry for demijohn, and the source material surfaced in this corpus is unrelated to the term — it concerns seisin language from property law. Researchers should not expect Black's Law Law or similar standard references to illuminate this term beyond its plain meaning.
Historical Dictionary Support
No major historical legal dictionary — including Anderson's, Bouvier's, or Black's — treats demijohn as a term requiring legal definition. This is consistent with the word's character: it is a term of trade and common description that entered legal documents by necessity rather than by doctrinal development. Its absence from the legal dictionaries is itself informative, signaling that courts and practitioners understood it by its ordinary commercial meaning without specialized gloss.
Where historical sources are useful is in period trade manuals, customs schedules, and excise handbooks, which sometimes specify standard demijohn capacities for duty purposes. These sources sit outside the traditional legal dictionary tradition but are properly part of the historical legal research environment for taxation and commercial law questions.
Jurisdictional Note
No significant jurisdictional variation in the legal meaning of the term exists. Capacity conventions and the specific excise classifications in which demijohns appear vary by jurisdiction and era, which can affect research into duty liability or licensing thresholds, but the word itself carries the same descriptive meaning across common law jurisdictions.
